The most common systems for transmitting power from a drive to a driven shaft are belt, gear, and chain drives. But V-belt drive systems, also known as friction drives (because power is certainly transmitted consequently of the belt’s adherence to the pulley) are a cost-effective option for industrial, automotive, commercial, agricultural, and house appliance applications. V-belt drives are also easy to install, require no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slide and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is important to choose a belt befitting the application accessible.
Belt drives are among the earliest power transmission systems and were widely used through the Industrial Revolution. After that, toned belts conveyed power over large distances and were created from leather. Later, demands for better machinery, and the growth of large markets like the automobile sector spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the increased overall surface material of modern belts adheres to pulley grooves through friction push, to reduce the tension required to transmit torque. The top portion of the belt, called the strain or insulation section, contains fiber cords for increased strength as it carries the load of traction power. It helps hold tension members set up and functions as a binder for higher adhesion between cords and other sections. This way, heat build-up is reduced, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat resistance with OE quality match and structure for reliable, long-enduring performance.
V-Belts are the most common type of drive belt used for power transmitting. Their V Belt primary function is definitely to transmit power from a principal source, like a engine, to a secondary driven unit. They provide the best combination of traction, velocity transfer, load distribution, and extended service life. The majority are limitless and their cross section is definitely trapezoidal or “V” shaped. The “V” form of the belt tracks in a likewise shaped groove on a pulley or sheave. The v-belt wedges into the groove as the strain increases creating power distribution and torque. V-belts are generally made of rubber or polymer or there may be fibers embedded for added power and reinforcement.
V-belts are generally within two construction types: envelope (wrapped) and raw edge.
Wrapped belts have a higher level of resistance to oils and intense temperatures. They can be used as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, increase power ratings, and provide longer life.
V-belts appear to be relatively benign and simple devices. Just measure the top width and circumference, discover another belt with the same dimensions, and slap it on the drive. There’s only 1 problem: that approach is about as wrong as you can get.
